Abstract

We present recent progress in development of high power directly diode pumped lasers based on the Yb:YAG thin-disk technology which are being constructed at the HiLASE project in the Czech Republic. Up to three laser chains, each delivering more than 1 J in 1 ps pulse with 1 kHz repetition rate should be built until 2015. In order to overcome technological barriers and optimize the amplifiers which are under construction, a new time-resolved numerical model suitable for describing of quasi-three-level active media operateing at room temperature in the thin-disk laser head is being created. The model is based on Monte Carlo ray-tracing and considers decreasing of the upper laser level population due to the amplified spontaneous emission. In the near future, the model will be used for optimizing of a 2- heads Yb:YAG zero phonon line pumped regenerative amplifier delivering up to 100 mJ in 1 ps pulse and 1 kHz repetition rate.
